Description Attachments

The WAV Trigger from Sparkfun is a high-fidelity, polyphonic audio player with the ability to support up to 2048 uncompressed 16-bit, 44.1kHz wav files – the same quality as an audio CD. It can play and mix up to 14 stereo tracks simultaneously and independently, with very low latency. Tracks can be controlled via 16 programmable trigger inputs, or by using a native serial control protocol or even MIDI.

This device is not just an audio player; it can be connected directly to switches and buttons, or to digital outputs from sensors or another microcontroller. You can specify alternate functions using a free cross-platform GUI application, which allows triggers to play sequential or random tracks, pause and resume groups of tracks and even control volume. An Arduino library allows for complex serial control like real-time mixing, starting multiple tracks in sample-sync and smooth cross-fading between tracks.

The WAV Trigger is designed with an on-board sample rate conversion that allows for smoothly changing playback speed/pitch from 0.5x to 2x in real-time. This means you can adjust the speed or pitch of the audio without affecting the other.

With its MIDI capabilities, the WAV Trigger can be used as a polyphonic sampling synthesizer to play your own sounds from any MIDI keyboard controller. MIDI Channels and Note numbers are mapped to track numbers, and MIDI Controllers adjust volume as well as attack and release times. MIDI Program Change is supported to switch between up to 16 banks of 128 sounds. The WAV Trigger audio engine even implements pitch bending, voice stealing, note attack (fade-in), note release (fade-out) and latency averages 8 ms.

As for storage, the WAV Trigger supports both SDSC (up to 2GB) and SDHC (up to 32GB) type microSD cards, providing ample space for your audio files.

This product is a collaboration with Robertsonics, with a portion of each sale going back to them for product support and continued development.
